Company: Nortek Air Solutions

Product: Computer Room Air Handlers (CRAH)

Description: Designed and released with several models ranging from 9,000 to 48,000 cfm or 63 to 430 kW nominal cooling power capacity, these units are designed to maximize cooling per square foot and require minimal kW input for efficient operation in a small footprint. The new catalog models supplement the company’s legacy custom CRAH platform, which will continue providing custom-built units to accommodate data centers requiring air handling systems with site-specific requirements. The new catalog units provide a comprehensive CRAH lineup for data center and mission critical applications, ranging from custom-built units for any conceivable specification to models that fill an economical, standard operation requirement. The products allow consulting engineers to specify end user desired options while achieving a cooling capacity the data center requires. The units are available with an optimized copper tube/aluminum fin A-frame coil; however, an optional high-capacity coil is available to achieve a greater cooling capacity in the same footprint. Additional configurability comes in fan selection. The CRAH offers two-fan, three-fan, and four-fan options, which can be selected and optimized to balance performance, cost, efficiency, and project requirements. Supply air discharge can be selected with the most common configurations — downflow for underfloor applications or front discharge. Each model uses ECM fans with an AMCA-certified performance in a horizontal FANWALL® configuration positioned below the cooling coil.
